Question about New Delhi: anemia dropped from National Family Health Survey (NFHS-6) is scheduled to start on July 6 after several experts said the method used for the estimation was inadequate. anemia in the investigation It was flawed and led to overestimation. Additionally, anemia is expected to be investigated as part of the study. Diet and biomarker investigation in India (DABS-I), preparations began in December last year.
In 2019-21 NFHS-5, prevalence of anemia Significant ‘unexplained’ increases were seen in nearly all sections, with the most dramatic increases (59% to 67%) in children aged 6 months to 5 years.
According to experts who attended several meetings of the Ministry of Health and Niti Aayog, a decision was made there to stop the anemia. NFHS A problem with the NFHS estimation was that it used blood drawn from capillary samples or finger pricks and was subsequently measured using instruments where results could differ by almost 1 gram per deciliter of blood.
In a study published in The Lancet based on data from the Comprehensive National Nutrition Survey (CNNS) of India in 2019, the authors found that “data, including field data from India, showed higher hemoglobin estimates (up to 0.6 0.9).” g/dL) is better for venous blood than for capillary samples. A venous sample is a blood sample taken from a vein, and its use is said to be the gold standard for estimating anemia.
” DABS– I do research and make maps dietUsing standardized venous samples and automated analyzers in the ICMR-NIN lab, we analyze nutrition and health status to provide accurate estimates of anemia in urban and rural populations. This is the first time such a detailed study has been done using biomarkers. The study also provides nutritional content data for cooked and uncooked foods for all regions and states in the country. NFHS uses district representative sampling, while DABS uses state and national representative sampling. DABS-I pilots are underway in he 12 states, and fieldwork for the investigation is expected to begin in the coming weeks,” explained Dr. Hemalasa R., Director of the Institute. National Institute of Nutrition, In Hyderabad, where the study will be conducted with ICMR, NFHS will be conducted on a sample of nearly 700,000 households and DABS will be conducted on a sample of 180,000 people across India. DABS is expected to be completed within a year.
